In my application by an error we powered the ADG726 with 3.3. volt but inputs applied were 5 volt through series resistor for few hours and at output of mux maximum signal level was 4 volt, which resulted in the wrong system behavior (subsequent FPGA device connected to mux output detected the wrong logic).
Afterward we corrected the mistake and mux was powered with 5 volt and inputs were same 5 volt signal through series resistors and system behavior was correct.
My question is whether we have caused any permanent damage to mux chip ADG726 or stressed it? .
Can i continue to use the same chip in my application without replacing it?
Kindly give your opinion given this system is used for --telemetry applications.
Thanks and Regards
